ATTORNEY Patented Mar. 28, 1 950 REGISTERING DEVICE Daniel Broido,Cockfosters, near Barnet, England Application March 21, 1947, Serial No.736,130 In Great-BritainaApril 4, 1946 Claims. 1,

This, invention relates. to registering devices, particularly. tototalizing registers of calculating, adding, accounting, .tabulating,and the like machines. More specificallystated, it relates to thevalue-entering-mechanisms. of totalizing registers.

It-is frequently desirable to enter into a totalizing register aplurality: of dilferent numerical values simultaneously, and for thispurpose it has been previouslysuggest'ed"to use differential 1mechanisms, for instance. of the: rack-and-gear type, ,or.- of, thebevel-pinion type, or of the sunandeplanet gear; type, and soiorth.These, mechanismswork'zsatisfactorilyr when the number of input: values;to: be entered. into, the totallzer simultaneously-is small, butdifliculties arise when the numberrof :input: values increases. Inmechanismsofrthis .typezit is necessary. tozcouple every two inputmembers, to;- a'. first output member,

then to couple every twoffirst output members to-a secondoutputf member,andsoforth, until the, final output member-is reached; Thisconsiderably; increases. the number. of components, increases. frictionand, back-lash; and. also considerably reducesthe movement of the outputmember as compared with that of an input member:-.

' The main: objectiofv the present. invention is to; deviseaad'nferentlal value-een-tering' mechanism forytotalizingregisterswhich, .while being easy to :manufacture, e. compact, andaccurate: in operatiom wouldgpermit simultaneous readout and speedy,entry of aplurality of values into the same, registering elements of thesaid. totalizers.

Another obiectiseto devise a differential valueentering mechanism.wherein the output movement'is equalto the number of inputmovements.

Another'object .isto devise a sensing and valueentering; differentialmechanism wherein any value entered. during, the sensing operationproduces a corresponding movement of the final output member during thesubsequent driving operation, without any intermediaryoutput members-..

Yetafurther object isto devise a.high-speed difierential; value-enteringmechanism wherein the output .memberis-positivelydriven by a drivingmember making the same. predetermined stroke during each operating cycleirrespective of thedlfferentialmovement of the said output member.

Anotherobject'is to devise 'a differential valueentering mechanismwherein the output member is positively: driven' by a transmissionmedium brought 'lnto operative association with a driving member havinga predetermined stroke, the amount of movement of the output memberbeing equal to the total quantity of the transmission medium broughtinto operative association with said driving member.

A further object is todevise a high-speeddifferential value-enteringmechanism having a minimum of springs, and also having means forprevention of overthrow and rebound ofthe output members operating thetotalizing register.

Other objects will become apparent as the description proceeds.

With these objects in vview, a differential valueentering mechanism fora totalizing register made according to the present invention comprisesone conduit for each denominational register"- ing element of thetotalizer, each conduit comprising a first section normally filled witha transmission medium readily divisable into a plurality of elementaryquantities, a second'section for temporary storing quantities of saidtransmis'sionmedium and a third section serving as a return passage fromthe second section to the first section, a plurality of input membersoperatively associated with each conduit and each adapted to cause apredetermined quantity of said transmission medium to move from thefirst. section to the second section of the re"- spective conduit;driving" means for'driving the said transmission medium from thesecondse'ctions into" the third sections and thence back into the firstsections of the said conduits, means 'for reciprocatingthe-said drivingmeansthrough a predetermined stroke during each opera-ting cycle, outputmembers each associated with one of said conduits and adapted tobedrivenby said transmission medium, while the latter is being driven bysaid driving means, through a distance proportionate to thetotalouantity of said transmission medium previously moved into thesecond section of the respective conduit, means for restoring the saidinput and output members, and. .means for coupling the denominationalregistering elementsorthe totalizer to the respective output members.

From another aspect, a sensing and valueentering differential mechanismmade according to the present invention comprises one conduit for eachdenominational registering element-of a totalizing register, eachconduit comprisingafirst section normally filled, With a transmissionmedium readily divisable into a plurality of elemenand a third sectionserving as a returnpassage from the second section to the first section,a plurality of sensing members associated with each of said conduits andeach adapted to sense a certain numerical value to be entered into therespective denominational registering element of the totalizer, inputmembers each operatively associated with one of said sensing members andadapted to move a quantity of said transmission medium proportionate tothe sensed valu from the first section into the second section of therespective conduit, driving means for driving the transmission mediumfrom the second sections into the third sections and thence back intothe first sections of said conduits, means for reciprocating the saiddriving means through a predetermined stroke during each operatingcycle, output members each associated with one of said conduits andadapted to be driven by the said transmission medium, while the latteris being driven by said driving means, through a distance proportionateto the total quantity of said transmission medium previously moved intothe second section of the respective conduit, means for restoring thesaid sensing members, input members, and output members, and means forcoupling the output members to the respective denominational registeringelements of the totalizer.

The invention may be applied to any machine having a totalizingregister, such as a calculating, adding, or like machine in order toachieve, in an eflicient manner, a simultaneous read-out and entry of aplurality of numerical values. In the preferred embodiment about to bedescribed, the invention is applied to a sterling calculating machine,but it is not limited to the sterling system and may be used for anynumerical system, including the decimal system.

General arrangement The machine comprises, generally, a supportingstructure, a set-up mechanism, a sensing and value-entering mechanism, atotalising register, a revolution or multiplier register, a driving andoperating mechanism, and associated devices. The general arrangement ofthe machine is shown in Figure 18, wherein the set-up mechanism isgenerally indicated as at M, the totalizing register as at I66 and therevolution register as at 288.

The supporting structure comprises a base plate I, two inner side frames2, 3, Figure 15A, 15B, and two outer side frames 4, 5, interconnected bya number of crossbars to form a rigid structure to which is fixed themachine cover 6.

Set-up mechanism A carriage formed by two side plates "I, 8, Figure 2,interconnected by crossbars such as 9, I0, II, Figure 1A, 1B, isarranged to move between the outer machine frames 4, 5 on rollers I2running in rails I3, I4 fixed to base plate I. A spring I5 in barrel Ittends to pull the carriage to the right, as viewed in Figure 2. A shiftlever I'I pivoted at I8 in carriage plate 8 engages a slot in anescapement pawl I9 pivoted at 20, Figure 4, in crossbar I0. Tooth 2| onpawl I8 is normally caused by a spring 22, Figure 1A, to engage atoothed rack 23 fixed to base plate I. When the forward end of shiftlever I1 is depressed, its rear end rocks the pawl I9 counter-clockwiseas viewed in Figure 4, so that tooth 2I is disengaged from mean and thecarriage is moved by spring Iii approximately a half-tooth space to theright, whereupon a I second tooth 24 on pawl I9 engages rack 23.

When the shift lever IT is released, it is restored by spring 22; pawlI9 is also restored and tooth 24 is disengaged from rack 23; thecarriage completes a one-space movement to the right, and tooth 2|re-engages rack 23.

The carriage is shiftable to the left bya handwheel 25 fixed to a shaft26, Figure 1A, journalled in crossbars 9, I0. Fixed to shaft 26 is agear 21 meshing with ,a rack .28 secured to base plate I. I

A shaft 29, Figures 1A and 2, is journalled in bearings 30 in carriageplate I, 8; Ten setting discs 3l-40, one for each set-up denomination ofthe machine capacity, are rotatably mounted on shaft 29. Setting disc 3|is associated with hundredths-of-penny denomination (D10* for short),disc 32 with tenths-of-penny (D10- disc 33 with pence (D), disc 34 withshillings (S), and discs 35-49 with units, tens, etc., of pounds (Ll-LlEach disc 31-49 has a finger tip 4|, Figure 1A, protruding through aslot in carriage cover 42, and a numeral strip 43 with numerals 0-9 or0-11 for pence, or 0-19 for shillings, respectively. Numerals on strips43 are visible through apertures 44 in carriage cover- 4 2.

Figure 18; furthermorathe carriage cover may be marked with appropriatenumerals (not shown) along the slots for fingertips 4|. Each disc 3l-49has locating teeth co-acting' with a ball 45, Figure 1A, biased byspring 45 in a housing 41.

Each setting disc 3l-4-9 is mounted on a boss 48, Figure 2, which has arecess or slot engaged by a pin 49 fixed to shaft 29; these slots aresufficiently long to allow for the maximum setting movement of discs31-49. A bracket 50 fixed to shaft 29 protrudes through a slot incarriage cover 42; it has a clearing knob 5| and is normally pulled downby a spring 52, Figure 1A. For clearing the set-up, clearing knob 5! ispushed upwards, thus rotating the shaft 29 clockwise; pins 49 pick uptheir associated discs 3|-49 and restore them to their initial positionsshown in Figure 1A, whereupon clearing lever 50 is restored by itsspring 52.

The setting movement of discs 3l-40 is utilised to position perforatedplates generally designated 53 in Figure 1B and more fully describedhereafter. .A set of plates 53 is operatively associated with eachsetting disc 3l49, the number of plates 53 within each set correspondingto the number of digital values in the respective denomination. Thus,the sets associated with setting discs 3|, 32 (D Dl0 and 35-40 (Lb-L19each comprise ten plates 53, one for each digit 0-9; the set associatedwith setting disc 33 (D) has twelve plates 53, one for each pence value0-11; and the set associated with disc 34 (S) has twenty plates 53, onefor each shillings value 0-19. As shown in Figures 113 and 3, plates 53of each set are mounted in a slide formed by rigidly interconnected endplates 54, Figure 3, top plate 55 and bottom plate 56 which has brackets57 fixedly supporting a pin 58. Each slide is mounted for independentvertical movement in pairs of guides 59 interconnected by end plates 50,SI and top plates 62 and secured to the carriage structure '1, 8. Thereare three pairs or banks of guides 59, the front bank containing plates53 associated with D, L10, L10 L10 and L10 denominations, as indicatedin Figure 3; the middle bank containing plates 53 of the DlU- and L1denominations; and the rear bank containing perforated plates 53 of theDID- S, and L10 denominations.

Settings discs iii-49 are connected with their respective slides in themanner shown in Figures 1A, 1B, 1C, and 2. Pivoted at 53. in disc 3| isa connecting rod 54 linked at 55 to a fork 66 pivoted on a shaft 61fixedly mounted in car riage structure i, 8. Fork 66 is slotted toengage pin 58 of the DIG- slide in the rear bank; front guide 591'sslotted to allow for free movement of the fork. Similarly linked to disc32 is a connecting rod 69 linked at B'QcfiOfOTk 19' rock-- able on shaft81; fork T9 is slotted to engage' pin 58 of the D10 slide in the middlebank. Seting disc 33 is linked at H to a connecting rod 12 linked at 13to a fork 14- pivoted at 15 in a bracket 75 secured to the carriagestructure; fork '54 engages pin 58' of the D slide in the front bank.Setting disc 34 is linked at T1 to a connecting rod 18 linked at '19 toa fork 89 pivoted at 81 in a bracket 92 secured to the carriagestructure; fork 9i engages pin 58 of the S slide in the rear bank. Discis linked as at 63' to a connecting rod 83 linked as at 69 to a fork 84pivoted on shaft 67 and engaging the pin 58 of the L1 slide in themiddle bank. Disc 35 is linked as at 53' to a connecting rod 95 linkedat 96 to a fork 8'! pivoted on shaft 6'! and engaging the pin 58 of theL10 slide in the front bank. Disc 3!- is linked as at 53' to aconnecting rod 88 linked as at tov a fork 89 pivoted on shaft 51 andengaging the pin 58 of the L10 slide in the rear bank. Finally, settingdiscs 38, 39, 4!] are linked as at 53 to connecting rods 99, 91, 92respectively, which are linked as at 86 to rockers 93, 94, 95respectively; these rockers are pivoted on shaft 51 and engage pins 58of slides L10 L10 L10 respectively, in the front bank of guides 59.

In this manneigwhen discs 31-40 are set so that the required numeralsappear in the apertures 44, the associated slides containing theperforated plates 53 are positioned accordingly. It may be noted thatwhile the setting, discs rotate around their shaft 29, the respectiveslides move vertically in a straight line. In order toproduce equalsteps of slide movement for each rotary step. of discs 3I-40, thelocating teeth on the discs may be spaced accordingly.

After the slides have been positioned vertically by setting the discs3l-40, the selected perforated plates 53 must be moved horizontally intooperative association with sensing pins 98, fully described hereafter.For this purpose each plate 53 is slidably mounted in slots formed inend plates 54 of each slide assembly. A pusher frame is mounted forhorizontal movement in line with the top (0) plates 53 when the slidesare in the lowest positions (shown in Figure 1B). This pusher frame canenter the slides through slots in guides 59 and thus push the selectedplates 53 forwardly (to the left as viewed in Figure 13) into theworking position shown in Figures 10 and 11, to be sensed by pins 96.The pusher frame, Figures 3 and 1B, comprises a forward plate 91, amiddle plate 98, and a rear plate 99, held together by strips I09; itfurther comprises floating plates NH, 102, I03, I04, I05 guided in slotsof the slide end plates 54. Further, floating plates Nil-I05, middleplate 98, and forward plate 91 are guided in slots on the sides of postsI secured to guides 59. Forward plate 91 is also supported in a slot ina double crossbar I91 fixed, to the carriage structure. Thus, each plate53 when aligned with the pushe frame is held between the elementscomprising the pusher frame, which are cut out to clear the slide endplates 54. Rear plate 99 of the pusher frame has. two brackets l 08 withbearings [09 through which passes a rod I I0. When this rod l H] ismoved forward as will be described in due course, the pusher framecauses those perforated plates 53 which are aligned with it to moveforward into the working position; when the pusher frame is restored byits rod 0, it restores the sensed plates 53 into the initial positionwithin the respective slides.
